There are no exact descriptions from physics or math for this, but
let's see if we can envision a temporal aperture more
vividly. We must rely on inductive reasoning and physical
analogies such as the antenna for this, and it may be subject to
modification. Words and ordinary logic fail us as expected.

To recap, any ordinary
antenna is surrounded by an aperture that is "visible" to the
radio waves (electromagnetic radiation) for which the antenna is tuned
(see page 13). That aperture is much larger than the physical antenna
itself and so is virtual to our eyes and must be imagined. Any
antenna engineer can clearly envision this aperture and define it
exactly, but we'll just be satisfied with imagining a large nominally
invisible volume around the antenna. Any other metal objects -
particularly ones that have a design resonance - that are introduced
into that antenna's aperture will effect its performance. No need
to touch the antenna structure physically - just be within the antenna's
defined aperture.

The antenna is usually a simple static device
with a single defined purpose. It's aperture reflects those basic
traits. The antenna is a device which functions to capture an
incoming carrier and focuses it ultimately for processing in a detector
where its content can be retrieved, such as for example in a radio or
TV.

Of compelling analogical or metaphorical
interest is the fact that a broadband antenna structure such as the
trivial case of a rooftop TV aerial has a different size and shape
capture aperture for every channel of its tuning.

Let's consider expanding the idea of capture. We'll ignore the
reciprocal concept of transmission until later since antennas typically
can both capture and radiate at their design frequency. Let's make
the leap to considering our entire consciousness and awareness as a
giant, infinitely complex capture phenomenon not unlike the single
defined purpose system of a physical antenna and receiver. With
consciousness and awareness we capture a continuous spray of sensations,
perceptions, and concepts and then dynamically integrate those to form
our ongoing here-and-now experience through time. It's like an
antenna and radio but much more complex. In an infinite universe, that
complexity potentially extends to an infinite number of dimensions
beyond our highly limited and and limiting three dimensions. Our vision
of and within the universe is always incomplete unfortunately.

If
one could cognize absolutely every object and event that ever has been,
is, or will be in every dimension, then one's temporal aperture would be
a volume of infinite size. It would comprise the entire universe, and
one would be a bona fide Deity or God. One could have knowledge of
Everything, all within the present here-and-now experience. As
one's
knowledge is much more limited - as is the time frame over which one can
play that knowledge - the aperture surround is much smaller than
infinite. It is functionally finite but may be potentially
infinite. It is in essence much larger than the physical self as with the antenna
but has finite and dynamic dimensionality for all practical purposes. It
is the sum total of all the possible cogniscent connections one can make
at any given moment.

One can imagine
then being surrounded by a large poly-dimensional volume of dynamic
irregular shape. Moreover, one's own volume intersects those of others
and may be contained within extended volumes of poly-dimensional
entities which we can't directly define in so many words, but that must
be present in an infinite universe. By analogy with the ordinary TV
aerial example above, the size and polydimensional "footprint"
of one's temporal aperture varies depending on the specific
consciousness area under consideration - the "channel".
One's temporal aperture in the light of higher mathematics may be small
and constrained but very large in the light of music. Another person's
temporal aperture in the horticulture "channel" may be large
but very small in the light of cooking skills. Etc., etc. The
instantaneous strengths and weaknesses in your awareness profile
determine the size and shape of the temporal aperture across all
dimensions.

What are the implications of
the temporal aperture intersecting with those of other people,
especially in unknown extradimensional areas? Could this be the
basis of the "vibe", "ESP" and other psi events, and
so forth?

If we propose extradimensional entities, aren't we getting
into spiritualism or even saying "Yes there is a God"?

Does
the temporal aperture actually ever become visible or directly sensed or
felt?

An antenna is typically bidirectional as is the pathway
through which it captures. So it can transmit as well as receive. We
clearly "transmit" and "receive" as we communicate
day-to-day with other people, but what about at those higher unknown
dimensions that are a part of our temporal aperture? Maybe this is where
we "get a feeling" or "hunch" about something?
Is this where psi events happen and then filter down roughly to our
normal waking consciousness?

The
implications of the expanded temporal aperture model are literally all
encompassing, and that's why it is a "unifying model of
consciousness". Spiritualism of all types, psi events, e.g,
ESP, and everyday waking consciousness all fall under the umbrella of
the temporal aperture model.
